ores as imported at Middlesbrough in 1890 and 1900.    The comparison is as follows:
1890                1900
Fe dry......................    55.50               52.80
Water......................      9.00                 9.10
Fe as received.................    50.50               47.99
Silica......................      7.10        '       10.09
The ocean freight is usually 30 cents higher than the figures just given, which would make the ore cost $3.94 per ton, or about $7.60 per ton of iron. The silica runs about one-half as high as in the Cleveland stone, and the limestone needed is less, and the'fuel will be about 0.95 tons per ton of pig-iron. The cost, therefore, of the ore, fuel and stone for a ton of hematite pig-iron will be as follows :
Ore ...........	Low freight. ...........    $7.06	Usual freight. $7.60
	. . . . .......      2.66	2.66
	............ 50	.50
		
$10,22
$10.76
Adding the same amount for labor and supplies as in the case of Cleveland iron, viz., 85 cents, the cost of hematite iron is from $11.10 to $11.60, not reckoning general expense or interest. In the winter of 1900-01 the selling price was about $13.85 per ton.
